Problems with booting after installing Ubuntu 9.10


Hey, i installed Ubuntu 9.10 on an external hard-drive according to an online guide i found. The first problem i ran into was that Grub takes ages to load, however, after it's loaded, i am able to choose what OS to start(i have windows vista of my computers hard-drive). The second problem is that i am now unable to start windows vista without having my external hard drive (the one that Ubuntu is installed on) connected to my PC, it just says something like "Loading grub....no such disk". Im really worried that i've done something irriversible.

Please answer keeping in mind that i have almost no knowledge of linux operating systems at all.

Grub placed itself on your windows hard drive and is looking for your external drive for a list of boot selections. It can't see your external drive and you get what you are seeing.

There are solutions to your problem depending on what you're after. I think what you probably wanted was to have your boot priorities set as your external drive first and then it would have had grub on it rather than your windows hard drive. If so, I'm sure there are many on this forum who could help you get to that state.

Well after reading the link you gave I could not understand but based on the discussion upto this point here I feel that you have installed grub on your hard disk not MBR.

Since when there is an entry chainloader+1 it automatically passes the control to Vista Bootloader

You insert the Ubuntu cd choose repair mode or safe mode what ever it is and then

when you can get a root shell it will look with a # in it

type grub-install /dev/sda or /dev/hda what ever it is if it is a SATA hard disk it will be sda and if normal then hda.

Try to search on how to re install grub Ubuntu

If you're after what I suggested, your first step is to remove Grub from your Vista drive. Not familiar with Vista so I'm not exactly sure how you can restore that drive, but I'm sure it can be done. Next, you have to configure your BIOS so that boot priorities are external first, then your Vista drive. Then you can put grub on your external drive or just re-install Ubuntu.

Lou

EDIT: It may not be possible to set your boot priorities with two different hard drives. If not, we'll have to look at another approach.

Well no.I mentioned that I feel you have not installed Grub on MBR So
it is not there.
Suppose my guess is wrong and it was there then http://ubuntuforums.org/showthread.php?t=224351

I have forgotten that is there a command grub-reinstall just search it on google.

Okay... for some reason i thought after removing grub from my vista disk, i could just normally boot from my external hard drive into ubuntu without grub. Apparantly it doesn't work that way(dont laugh please).
I still get a screen where i can choose from booting into windows vista or ubuntu, but if i choose ubuntu, it won't work.
Could someone clarify what to do next?

If the Vista drive is still the primary drive and you're getting the grub menu, then you haven't removed grub from it.

If the external drive is now the primary drive and you didn't re-install Ubuntu, then you need to edit your grub.cfg file because your external drive is now hd0 instead of hd1. This is a little complicated and it would be easier if you just re-installed Ubuntu.

Well this directly will not answer your question but if you want to go ahead with Linux you may use some thing called Wubi installer with Ubuntu.
It will install Ubuntu in a folder http://wubi-installer.org/
